How IoT is Shaping the Future of Building Management Systems
The increasing focus on energy conservation, operational efficiency, and occupant comfort has ignited a technological revolution in building infrastructure. Leading this change is the integration of the Internet of Things (IoT) into Building Management Systems (BMS). These smart networks are transforming how buildings function, moving from reactive systems to proactive, data-driven environments that adjust in real time to meet evolving needs. As buildings grow smarter and more responsive, the combination of IoT and BMS stands out as a key driver of this advancement.
Ashok Kumar Kalyanam, a Subject Matter Expert and Solution Consultant, presents an in-depth exploration of this evolution in his whitepaper titled "Building Management System (BMS): An In-Depth Overview (Understanding BMS, Its Operation, Necessity, and the Role of IoT)". The whitepaper offers a comprehensive overview of how BMS technologies, traditionally reliant on manual inputs, are now using IoT to unlock new levels of automation, efficiency, and adaptability.
'Building Management Systems are no longer just about control, they're about intelligence and insight,' he explains. His work traces the journey of BMS from rudimentary monitoring platforms to sophisticated, interconnected ecosystems. These systems oversee HVAC, lighting, security, and safety components, working in harmony to reduce energy waste, lower operational costs, and elevate user experience.
One of the major points of emphasis in the whitepaper is the contribution of IoT towards revolutionizing contemporary BMS. With the incorporation of smart sensors and IoT-based devices, including occupancy sensors, motion sensors, and environmental sensors, BMS platforms can now receive real-time data streams. This real-time feedback loop enables predictive maintenance, adaptive resource utilization, and highly individualized building environments.
Kalyanam outlines four core benefits that stem from the convergence of IoT and Building Management Systems. First, energy efficiency is significantly enhanced as automated systems adjust HVAC and lighting based on real-time occupancy and ambient conditions, reducing energy waste while aligning with cost-saving and sustainability goals. Second, predictive maintenance becomes feasible through continuous monitoring, enabling early detection of system anomalies and wear, which minimizes downtime and extends equipment life. Third, operational efficiency is achieved through remote control capabilities and centralized dashboards that allow facility managers to oversee and manage multiple systems simultaneously, resulting in faster response times and refined operations. Lastly, the integration delivers an enhanced user experience by allowing greater personalization;occupants can use mobile interfaces to control lighting, temperature, and other settings to match their preferences, leading to improved comfort and satisfaction.
The whitepaper doesn't limit itself to theory. It features real-world case studies from industry leaders like Honeywell, Johnson Controls, and Tridium, showcasing how IoT-powered BMS platforms have been implemented at scale. These companies are using communication protocols such as BACnet, Modbus, and Zigbee to ensure interoperability across devices and systems. The result is a modular, scalable approach to building intelligence that accommodates a wide range of facilities, from office towers to healthcare campuses.
Despite the remarkable progress, he carefully acknowledges the challenges that remain. Data privacy, cyber-security, and compatibility across devices present real obstacles. 'As we connect more components, ensuring secure and standardized communication becomes a priority,' he notes. Addressing these challenges will require a combination of robust policy frameworks, advanced encryption protocols, and collaborative industry standards.
Looking ahead, the paper forecasts an increased usage of AI and ML tools whereby BMS capabilities can be enhanced. These tools would enable real-time optimization, autonomous fault detection, and even self-healing systems that learn and adapt to usage patterns.
In conclusion, Ashok Kumar Kalyanam's whitepaper, "Building Management System (BMS): An In-Depth Overview", is a compelling examination of the transformative role of IoT in modern building systems. Through expert insights, technical frameworks, and practical examples, it illustrates how connected infrastructure is not just a trend, but a foundational pillar for smarter, more sustainable buildings. As the world moves toward greater urbanization and environmental responsibility, IoT-enabled BMS will be instrumental in shaping the future of intelligent living and working spaces.

Cut-offs drop in 3rd list; CET results of BMS & BBA may cause seat shift
Mumbai: While some of the leading colleges have closed admissions for their popular courses, such as BA Psychology, after the second list, the cut-offs for other courses, even in other subject combinations for BA, have seen a drop in the third list — some are steep when compared to the first list. Many colleges said they did not get enough applications for BSc to even put out a third list. Even as the Mumbai University (MU) extended the deadline for degree college admissions till June 15 and CET results of BBA/BMS/BCA were out, colleges are now worried about horizontal mobility of students to other courses in the same college. At Jai Hind College, BA saw the sharpest fall, dropping from 92.17% from the first list to 80% in the third, but the psychology seats are already full after the second list. Overall, the third merit list reflected a moderate decline across most courses. BBI registered the largest drop among self-financed programmes, slipping by 3.5 points from 90% to 86.5%. Principal Vijay Dabholkar said their new courses in international accounting and actuarial science and quantitative finance were full. "Many students these days are following social media influencers who are promoting new-age, skill-oriented courses, and therefore there is a huge demand for them. Also, now that the CET results for BBA, BMS is out, many students will leave their existing seats to go for them," he said. Karuna Gokarn, principal, St Xavier's College, said they did not have a third list for most of their courses, except BA, for the subject combinations other than psychology. She said the situation in science is grim. It could not only be because of the new professional courses, but also due to undergraduate science courses in institutes such as IISER and IITs picking up and students preferring it over leading autonomous colleges. At Podar College, commerce programmes remained largely stable — BCom financial markets declined slightly from 94.5% to 92%, and BAF, which opened at a high 95.6%, closed at 93.4%. At Ruia College, third merit list for BA course closed at 84%. Most colleges are expecting cut-offs to improve in the fourth and fifth round. The university issued a fresh schedule on Thursday to include students who were left out from the previous process.

Alternative data sources help in 'proactive intervention' for growth: CEA
Alternative data sources arising as the 'byproduct of everyday digital interactions' can help policymakers in providing "proactive intervention" for economic growth, said V Anantha Nageswaran, India's chief economic advisor, on Thursday. 'It is important to note that the value of alternate data is not in its volume or novelty, but in the distinctive lens it offers,' he said at the National Workshop on Alternate Data Sources and Frontier Technologies for Policy Making. The two-day event in New Delhi is organised by the Ministry of Statistics and Programme Implementation (MoSPI). 'These data sources enable policymakers to move from retrospective diagnostics to proactive intervention. It captures emergent behaviour and reflects the lived experience of economic agents that conventional aggregates sometimes cannot.' It is important that researchers understand the huge amounts of data that is being generated, as it helps in improving the forecast accuracy of economic aggregates such as consumption, gross domestic product and investments, said Nageswaran. 'For example, satellite-based night-time luminosity has been used to indicate economic activity in regions with delayed or weak statistical reporting. The satellite data can help policymakers detect cropping patterns, assess soil moisture, and detect early signs of drought. These insights can inform timely decisions on input provisioning, crop insurance payouts, and regional procurement strategies.' Suman K Bery, vice-chairperson of NITI Aayog, told the workshop conventional data should be integrated with alternate sources while ensuring quality. 'The insights from traditional as well as alternate data sources need to be strengthened with emphasis on data processing and assimilation at the same time,' said Bery. Saurabh Garg, secretary at MoSPI, listed five building blocks for enhancing harmonisation of data. These are meta data structures, international and national classifications, unique identifiers, self-quality assessment tools and reconciliation of diverse data to achieve such endeavours. Nageswaran said data generated by statistical systems and alternate sources complement rather than substitute each other. The latest trends in technology, like artificial intelligence and Internet of things, have to go hand in hand with skilling manpower.

Want to add 10 million jobs, India? Walking away from "take-make-waste" model alone will do
What does it truly mean to grow, if growth comes at the cost of the very systems that sustain us? As the world reflects on the mounting threat of plastic pollution this World Environment Day, we must also examine the deeper architecture of waste that underpins our economies—one that extends far beyond plastic into the very way we produce, consume, and discard resources. Globally, around 90 billion tonnes of natural resources are extracted annually, equivalent to more than 12 tonnes per person. Yet, only 7.2% of materials are cycled back into productive use after their first life. If we persist with our current "take-make-waste" economic model, this figure could double by 2050, pushing environmental thresholds and leaving a trail of unmanageable waste. The answer to this challenge lies in the transition from linear growth models to circularity. And what makes it more than a solution to an environmental concern is the economic opportunity it presents. Globally, the transition towards a circular economy represents a USD 4.5 trillion growth opportunity by 2030. For a country like India, transitioning to a circular economy could unlock a market value of over $2 trillion by 2050 and create nearly 10 million new jobs, especially in materials recovery, repair services, and circular manufacturing. In a nation navigating both rising consumption and growing inequality, circularity offers a bridge between sustainability and inclusive development. India has made promising early moves in this direction. The Extended Producer Responsibility (EPR) framework and the E-Waste (Management) Rules reflect policy intent. NITI Aayog's strategy for a circular economy outlines sectoral plans for 11 industries. More recently, the Resource Efficiency and Circular Economy Industry Coalition (RECEIC), launched during India's G20 presidency, signalled the intent to mainstream circularity in industrial ecosystems. The Swachh Bharat Mission has also already been mobilising a behavioural shift around waste in the country. But, as we make progress, the challenge of balancing growth with sustainability must be addressed with approaches tailored to respective sectors. To take the example of the renewable energy sector, which I have had the opportunity to witness and be a part of for over a decade now, a critical question remains underexplored: Is our renewable energy transition circular by design? India's ambition to install 500 GW of non-fossil fuel capacity by 2030 is a national imperative, and with ~220 GW capacity achieved, we are well on our way to this target, supported by a conducive policy environment. But this scale of growth also comes with material consequences. As per data, India could generate over 340,000 tonnes of cumulative solar PV waste by 2030. Globally, more than 90% of decommissioned solar panels end up in landfills today. Without urgent intervention, we may be solving one problem—carbon emissions—while inadvertently creating another. One overlooked aspect is the role of plastics in the solar PV value chain. From polymer-based back sheets and encapsulants to junction boxes, plastics are embedded in every panel. Still, these components are rarely recycled due to a lack of separation technologies or material recovery incentives. The result? A growing stockpile of future e-waste. How do we solve for this? India currently has fewer than 15 registered PV recycling units, and there is no dedicated regulation to manage solar waste. This is a space where more proactive planning and innovation can flourish. I see three ways to do this: 1. Clear national guidelines for the decommissioning of solar and wind assets, expanding the Extended Producer Responsibility framework to cover renewable energy equipment, and embedding circularity criteria into public procurement norms. 2. Targeted investments in research and development are needed to improve material recovery and to encourage innovation in modular, repairable system designs that extend product life. Businesses, too, must operationalise this shift by adopting service-based models like solar leasing that incentivise lifecycle accountability, and by building partnerships with recyclers to create scalable take-back schemes. 3. Finally, we need greater transparency and Traceability across the value chain, supported by an open digital registry of clean energy assets to track their lifecycle and manage end-of-life recovery. Some encouraging signs are already emerging. There are companies around the world that have recovered up to 90% of materials from decommissioned panels. Of course, circularity does not begin and end with industry. The government can draw from global best practices, such as Japan's city-level circular districts or the Netherlands' procurement-led material innovation. It must also align fiscal and regulatory levers to reward circular behaviour. Citizens, too, play an important role by embracing shared, localised systems of energy access, advocating for sustainable choices, and participating in community-led reuse and repair initiatives. A truly circular economy will require deep collaboration across disciplines and stakeholders. It will mean rethinking value, embracing restraint, and designing for longevity, not just convenience. This World Environment Day, let us move beyond symbolic gestures. Let us commit to building systems that do not just reduce harm but actively regenerate. Because the time to rethink, redesign, and regenerate is not tomorrow, it is now. (Vaishali Nigam Sinha is Co-founder and Chairperson, Sustainability, ReNew.)
